dinally or transversely of said handle, whereby the implement may beused as a pitchfork or a rake, as desired.`

To this end the present invention consistsl in the combination andarrangement of parts, as will be hereinafter more fully described, shownin the accompanying drawin gs,and particularly pointed out in theappended claims.

In the drawings, Figure 1 is a perspective view of the implementadjusted to be used as a pitchfork. Fig. Zis a longitudinal sectionalview thereof. Fig. 3 is a side elevation showing the implement adj ustedto provide a rake.

Fig.'4 is a detail perspective view of the shank of the fork orrake-head. Fig. 5 is a detail perspective view of the lockingcam-ring.Fig.

6 is a transverse sectional view taken on the line on ax, Fig. 3.

Corresponding parts are designated by like reference characters in allthe figures of the drawings.

Referring to the accompanying drawings, 1 designates the head of theimplement, having the usual tines 2 and a flat shank 3, having a lateralshoulder 4 provided upon one edge thereof and adjacent to the head 1,and a segmental extension 5, projecting laterally at right angles to theplane of the head and at one side only of the shank. Notches 6 and 7 areprovided in the outer periphery of the segmental extension 5, the notch6 being provided at the outer or free end of the eXtension, and thetooth S, formed between the two notches, is provided on its inner endwith a flange or shoulder 9, extending into the notch 7 and contractingthe mouth thereof. The head thus provided is adapted to be connected tothe handle 10 by means of a sleeve or ferrule 11, which is provided atone end with a socket 12, to receive the end of the handle,

and a longitudinal bifurcation 13 at the other end, within which theshank of the head is pivoted upon a transverse pivot-pin 14.

Mounted to turn upon the ferrule 11 at the base of the bifurcation 13 isaring 15, having opposite peripheral cam-flan ges 16, the spacedadjacent ends of the latter forming diametrically opposite notches orrecesses 17, adapted to receive the segmental extension of the fiatshank 3. The opposite edge of the ring is provided with the cam-faces18, located at right that when the implement is to be used as apitchfork the shank of the head 1 is received entirely within thebifurcation 13,-formed in the ferrule 11, and the lockingring 15 isturned axially, so as to engage one of the camianges 16 with the notch 7in the segmental extension 5, whereby the head 1 is effectually lockedagainst accidental movement. It will be noted that the cam-faces 18 ofthe lockingvring work against the lugs or shoulders 2l, provided uponthe ferrule, whereby said locking-ring is forced tightly against thesegmental extension 5, so as to prevent accidental ,turning or looseningof the ring.

To adjust the head to provide a rake, as shown in Fig. 3, thelocking-ring is turned to aline one of the notches or recesses 17 withthe segmental extension 5 and the latter is forced transversely throughthe bifurcation 13 upon the pivot-pin 14 as acenter until the free endof the segmental extension has passed beyond the opposite side of theferrule. It will be noted that this position of the segmental extensionis accurately provided for by' reason of the stop-shoulder 4 of theshank,3 engaging with a stop-shoulder 22 provided within the bifurcation 13.Then'the locking' ring 15 is turned axially to engage the oppositecam-ange 16 with the notch 6 formed in the segmental extension and thehead is then locked transversely of the handle of the implement.

IOO

The construction and arrangement hereinbefore described provide a simpleand durable implement, all of the parts of which are of substantial formand positively connected together and the device can be readily adjustedand eftectually locked against accidental displacement in either of itsadjusted positions.

Changes in the form, proportion, size, and the minor details ofconstruction within the scope of the appended claims may be resorted towithout departing from the spirit or sacriicing any of the advantages ofthis invention.

IVhat I claim isl. In an implement of the class described, thecombination with a bifurcated ferrule, of a tined head having a shankpivoted within the bifurcation and provided with a notched segmentalextension, and a locking ring mounted upon the ferrule and provided withflanges adapted to engage the notches of the segmental extension,whereby the head may be adjusted, substantially as shown and described.

2. In an implement of the class described, the combination with aferrule having a longitudinal bifurcation and diametrically oppositelugs or shoulders provided adjacent to the base of the bifurcation, of atined head having a shank pivoted within the bifurcation and providedwith a notched lateral segmental eXtension and a locking-ring mounted toturn upon the ferrule and provided with anges adapted to engage thenotches of the segmental extension, and cam-faces adapted to workagainst the lugs or shoulders of the ferrule, whereby the anges of thelockingring may be forced against the segmental extension of the shank,substantially as and for the purpose set forth.

3. In an implement of the class described, the combination with abifurcated ferrule, of a tined head having a shank pivoted within thebifurcation and provided with a notched lateral segmental extension, anda lockingring mounted to turn upon the ferrule and provided withdiametricall y opposite notches or recesses adapted to aline with thebifur cation and permit of the segmental extension being adjustedtransversely therethrough, and opposite flanges adapted to engage thenotches of the segmental extension, whereby the head may be adjusted,substantially as shown and described.

4. In an implement of the class described, the combination with abifurcated ferrule having a stop-shoulder provided at one side of thebifurcation, of a tined head having a shank provided with a lug orshoulder and a notched segmental extension and adapted to be pivotedWithin the bifurcation, and a ring mounted to turn upon the ferrule andhaving flanges adapted to engage with the notches of the segmentalextension, the shoulder of the shank being adapted to engage theshoulder provided in the bifurcation of the ferrule in one of the adjusted positions of the head, substantially as shown and described.

5. In an implement of the class described, the combination with abifureated ferrule having diametrically opposite lugs or shouldersadjacent to the base of the bifurcation,`of a tined head having a shankadapted to be piv oted within the bifurcation and provided with anotched segmental extension located at one side only of the shank andadapted to be adjusted transversely through the bifurcation andalocking-ring having diametrically opposite notches formed in one edgethereof, opposite cam-flan ges located at opposite sides of the notches,earn-faces provided at the opposite edge of the ring and adapted to Workagainst the lugs or shoulders provided upon the ferrule, and operatingthumb pieces adapted to engage the lugs of the ferrule and provide stopsfor the locking-ring, substantially as shown and described.

In testimony that I claim the foregoing as my own I have hereto aiiixedmy signature in the presence of two witnesses.
